Emcore Stands on Three Strong Legs of Light

Emcore Corporation (NASDQ: EMKR) a leading provider of Semi-conductor-based components and subsystems for the broadband, fiber-optic, satellite and terrestrial solar power markets. As of Feb 21, 2011 – the company's stock was up over 120% YTD. Why?

Emcore's IMM Solar Technology

Emcores' world record Inverted Metamorphic (IMM) solar cell technology was chosen by R&D Magazine for an R&D 100 award. This prestigious award recognizes the IMM solar cell as one of the most innovative technologies of 2008.

Developed in conjunction with the National Renewable Energy Laboratory (NREL) and the Vehicle Systems Directorate of the US Air Force Research Laboratory (AFRL), the IMM design is comprised of a novel combination of compound semiconductors that enables a superior response to the solar spectrum as compared to conventional multi-junction architecture. Due to its unique design, the IMM cell is approximately one fifteenth the thickness of the conventional multi-junction solar cell and will enable a new class of extremely lightweight, high-efficiency, and flexible solar arrays for space applications.

The IMM solar cell technology provides a platform for Emcore’s next generation photovoltaic products for space and terrestrial solar power applications. With the growth in demand for utlity sized CPV project s the IMM technology is now reaching the market and helping to push the companies stock upwards in 2011.

Space Photovoltaics

More than 1,000,000 flight-proven solar cells are powering over 90 satellites today.

Terrestrial Solar Power

For terrestrial applications, Emcore offers concentrating photovoltaic (CPV) systems for utility scale solar applications as well as offering its high-efficiency GaAs solar cells and CPV components for use in solar power concentrator systems.

Solar cells built using IMM technology have achieved a 39% efficiency level (which is expecte to increase to the 42%-45% range) when adapted for use under the 500-1500X concentrated illumination, typical in terrestrial concentrator photovoltaic (CPV) systems.

Furthermore, this technology can be readily integrated into Emcore’s complete line of CPV receiver products and the increased conversion efficiency will enable the most cost effective CPV systems.

Once fully commercialized, the CPV systems that are powered with EMCORE’s IMM based products will see a reduction in the cost of power generated by approximately 10% to 20%.

Emcore has developed a strong intellectual property position for this innovative technology, with over 10 patents pending in the area of solar cell design and manufacturing techniques.
